Description of the Related Art Conventionally, in an image information processing apparatus that performs image processing of medical images such as radiographic images, medical images such as radiographic images and their supplementary information are received from the image generation apparatus, and the received medical images and supplementary information are displayed and image processing is performed. The image is confirmed, and the image and supplementary information are output to an external image storage device, image forming device, image observation device, and the like. The image forming apparatus performs image formation based on, for example, film size information in the supplementary information. However, when the film size information is insufficient in the supplementary information, only the insufficient information is added on the image forming apparatus side. . The image storage device stores an image together with incidental information such as patient information and examination information.
[0003]
In the conventional image information processing apparatus, when the incidental information from the image generating apparatus on the input side is not sufficient, insufficient information cannot be added or the user needs to add it every time. In addition, since the incidental information received from a plurality of image generation apparatuses is different for each apparatus, it has been difficult to manage and operate the image information processing apparatus uniformly.
[0004]
In addition, the required information may be different for each of the multiple image storage devices on the output side, or unnecessary information may be different, which may result in insufficient information required for the image storage device and making it impossible to maximize its functions. The construction and operation of the entire system are restricted. In some cases, the image information processing apparatus cannot receive information necessary for operation / management on the image storage apparatus side or the image observation apparatus side without being transmitted from the image generation apparatus.

[0079]
Further, the storage unit 41 can add, change, etc. even if the supplementary information required for each of the plurality of image storage devices 54, 60 is different, and can provide supplementary information required for each output destination device even if there is no supplementary information. A second editing method set to be acquired and edited is stored.
[0080]
The supplementary information editing unit 21a of FIG. 3 edits the supplementary information based on the first editing method stored in the storage unit 41 for the supplementary information received from each of the plurality of medical image generation devices 51, 56, 57, and 59. Further, the auxiliary information is automatically edited based on the second editing method stored in the storage unit 41 before being output to each of the plurality of image storage devices 54 and 60. .
[0081]
Also, the incidental information editing unit 21a in FIG. 3 can acquire the items and contents of the incidental information from the HIS / RIS 58 when editing the incidental information. The edited supplementary information and the image-processed image are output from the output unit 43 a of the output image forming unit 43 to the image storage device 54 or 60.
[0082]
Next, the operation of the medical image information processing apparatus 50 of FIGS. 1 to 3 will be described with reference to the flowchart of FIG.
[0083]
First, the editing content and method for the supplementary information is set as the first editing method for each of the plurality of medical image generation devices 51, 56, 57, and 59 and stored in the storage unit 41 (S01). Similarly, a second editing method for editing incidental information is set for each of 54 and 60 and stored in the storage unit 41 (S02).
[0084]
As such an editing method, there is, for example, setting contents / methods such as addition / change / deletion for each item (or only necessary items) of the incidental information. The incidental information items include, for example, a patient ID, an examination instance UID, and the like, such as addition of a Chinese character name to a patient name and change of an SOP instance UID.
[0085]
Next, for example, after receiving a medical image and its accompanying information from the medical image generating apparatus 51 (S03), when editing the accompanying information by the first editing method set for the medical image generating apparatus 51 (S04). ), Editing is performed by adding / changing / deleting incidental information based on the first editing method (S05). If the supplementary information is not edited by the first editing method (S04), the received medical image and supplementary information are displayed on the screen of the image display device 22 (S06).
[0086]
Then, the medical image and the edited supplementary information are displayed on the screen of the image display device 22 (S06). If the displayed supplementary information needs to be changed, the user can perform information by operating the operation unit 21b. Is changed (S07), and the incidental information after the user change (which may not be changed) is temporarily stored in the storage unit 41 (S08).
[0087]
Next, for example, when editing the incidental information by the second editing method set for the image storage device 54 that is the output destination (S09), the addition / change / addition of the incidental information is performed based on the second editing method. Editing by deletion or the like is performed (S10). Since the medical image and the supplementary information are displayed on the screen, if there is a need to change the displayed supplementary information, the user changes the information by operating the operation unit 21b (S11), together with the medical image. The supplementary information after the user change (which may not be changed) is output to the image storage device 54 (S12).
[0088]
If the incidental information is not edited by the second editing method (S09), if necessary, the user changes the information by operating the operation unit 21b (S11) and outputs the information to the image storage device 54. (S12).
[0089]
In the above-described operation, the supplementary information is edited for the medical image generation apparatus 51. However, when the other medical image generation apparatuses 56, 57, and 59 receive the medical image and the supplementary information, the editing method is also adapted to the apparatus. The incidental information is edited. Further, although the incidental information is edited for the image storage device 54, when the output destination of the other image storage device 60 is the output destination, the incidental information is similarly edited by an editing method suitable for the device.
[0090]
As described above, according to the present embodiment of FIG. 4, even when there is a difference between supplementary information received from a plurality of medical image generation devices or there is no supplementary information, the supplementary information is added or changed. Since it is unified and sufficient incidental information can be obtained, subsequent image management and image operation in the image storage devices 54 and 60 are facilitated.
[0091]
Further, even if the format of the incidental information and the meaning of the items are different for each of the plurality of medical image generation apparatuses, they are unified, and display and operation to the user are facilitated. Further, since the incidental information output for each image storage device on the output side can be edited, the functions of each image storage device can be utilized to the maximum, and the range of system construction and operation is expanded.
[0092]
In addition, the user is not required to add the additional information that is insufficient each time, and the operation is simplified. In addition, incidental information is edited at the time of reception and output, respectively, and the addition of other devices or expansion connection does not affect the entire system, and can be easily performed.
[0093]
In FIG. 4, it is determined whether or not to perform the editing by the first editing method after receiving the medical image and the accompanying information and before displaying the screen (S04), but omits steps S04 and S05 and displays the screen. Thus, editing may be performed by the second editing method before output (S09, S10). Conversely, steps S09 and S10 may be omitted.
[0094]
In steps S04 and S09 described above, whether or not editing such as addition / change / deletion of incidental information is performed for each medical image generation apparatus or for each output destination apparatus is performed by the user operation unit 21b. However, it is also possible to determine whether or not to add / change / delete information for each item of incidental information.
[0095]
Further, when performing the above-described editing (S06, S10), the incidental information editing unit 21a of FIG. 3 may acquire the items and contents of the incidental information from the HIS / RIS 58.
[0096]
